SECTION 6. INSTALLATION WITH BYPASS LINE CAT recommends the use of a CAT Flowcell and Rotary Flow Sensor for all recreational water applications. The CAT Flowcell provides a controlled flow to maximize sensor life, convenient sample port for manual water tests, integrated mounting of Rotary Flow Sensor, and fast professional installation with flexible tubing and Tru-seal connectors. Construction of a bypass line should only be performed by experienced technicians familiar with the procedures for plumbing with PVC as well as the material used in the existing filtration system. Refer to Illustration 3 for a typical bypass diagram. 1. Turn off heater, chemical feeders, pump, and any other related equipment. Relieve pressure from filtration system. 2. Select a convenient mounting location for the controller unit which will meet the following criteria: A. Facilitates unobstructed bypass line plumbing. B. Located a minimum of ten feet from pool or spa. C. GFI protected power source available. D. Easily accessible to pool or spa operator. E. Away from corrosive materials and physical hazards. 3. Securely mount the CAT 2000 controller on a vertical wall. 4. Install one "reducing tee" or "saddle tee" fitting each on the incoming suction line to the pump and the return line upstream from heater as shown in Illustration 3. 5. Install ball valves on bypass inlet and effluent immediately adjacent to tee fittings. 6. Install in-line filter (optional) immediately downstream from bypass inlet valve. 7. Install flow meter (optional) immediately downstream from in-line filter (if applicable) or bypass inlet valve. 8. Install two tee fittings to accommodate ½" NPT Professional Series pH & ORP sensors as shown in Illustration 3. 9. Install Rotary Flow Sensor in bypass line as shown in Illustration 3.
